DRINKING-FOUNTAIN HEAD.

l Application tiled November 21, 1917. Serial No. 203,161.

To all whom t may concern Be it known that I, ROBERT JAMES EAST,

of the city of Winnipeg,l in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Drinking- Fountain Heads, of which the following is the specification.

The invention lrelates to improvements in drinking fountain heads, particularly as provide a head which delivers the stream to the side whereby the water after falling from the lips or mouth of one drinking does not again come in contact with the head` but falls into theY basin.

Al further object of the invention is to provide the head with a. detachable mouth ring which will prevent the lips from contactingV with the head and which will allow of the ring being removed and disinfected from time .to time.

A' still further 4object of theinvention is to provide a drinking head which can be readily converted from a valve controlled type to a constant'stream type. y f

With the above more ji portant objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later Hpointed, outY in the appended claims, reference being had to the accompanying drawing in which:- i I Figure 1 represents a frontview of the appliance as set up in a bowl.

Fig. 2 represents an enlarged detailed longitudinal sectional view centrally through, the head.

Fig. 3 represents a side view of a part of the head. Y

Fig. 4 represents a horizontal sectional `view lthrough the head, the section being taken in the plane denoted by the line X-X and looking downwardly.

Fig. 5 represents a horizontal sectional view through the upper end ofthe vstand pipe, the section passing through the slot therein,

Fig. 6 represents a horizontal Sectional view through .the edinisill mbe.

Fig. 7 represents a vertical sectional view centrally through the appliance showing the construction modified to provide ahead of the constant stream type.

In the drawing like characters of reference indicate corresponding parts in the several figures.

1 represents the usual draining bowl Or ycatch basin usually employed in private and public places where a drinking fountain is installed.

Such a bowl present-s a nected with a water main and a drain pipe 3 leading from the bowl. The pipe 2 cus.- tomarily terminates centrally of the interior of the bowl and to this pipe the fountain head is attached.

Where myy fountain head is employed l connect a T-.elbow 4- to the upperend of the pipe 2 and to the T-head I secure a shortlength of horizontally disposed pipe 5 fitted with an upturnedelbow 6 which carries the head. The T-elbow is fitted with a controlling valve 7 which can be regulated as desired and which can be reached by a suitable tool after the inclosing cap 8 has been removed.

The pipe 5 is of such a length that when the head is attached to the elbow it takes a position more or less to the side of the bowl. The head comprises the following parts:-

9v represents an upper cylindrical casing having the upper end thereof closed by it suitably shaped screw cao 11 and the lower end thereof closed and provided with outletl drain holes 10 and carrying an extension 13 forming'a valve chamber. The lower end of the extension is screw threaded as shown at 14 on to the upturned end of the elbow 6 so that the headtakes an upright posit-ion in respect to the bowl.

Specification yof Letters Patent. Patnted July 16, 1918.

feed pipe 2 con- 15 .represents a stand pipe having vthe lower end thereof secured in any suitable manner permanentlyV to the inner end of vpasses slidably through the` end 16 of the stand pipe and slidably through. a boss 2O carried by the head while the lower end passes .slidably @brauch the .lamer` @ad of has a natural tendency to force the stem up Y vand normally hold the valve closed.

The stem is bored longitudinally yat 24 to Y provide an admission duct having vthe inlet end 25 opening to the side ofthe stem in a location adjacent the valve and the upper end opening to the side oit the stem at 26 in a location somewhat below the slot 18. F rom this arrangement it will be obvious that when the valve is closed no water can enter the duct from'the valve chamber throughl theY opening but that upon the valve being uiiseated the opening 25 communicates with the interior of the valve chamber andallows of a flow from the valve chamber through the duct and into Vthe stand pipe through the opening 26, Y

`27 represents an upwardly inclined side nozzle communicating with the'lower end of the ,stand pipe and adapted toej'ect a stream of water through a suitable slot or side opening 28 formed in the side of the casing 9.

29 represents a mouth ring which is oval in shape and of such a size that it will completely surround the mouth clear of the lips. 'This ringiis placed in an upright position and positioned so that the stream discharged throughl the opening 28 from the nozzle will pass more or less centrally through `the ring. The ring is spaced from the c asing by upper and lower legs 30 and 31 and is detachably secured to the same in any Y suitable way such as by a pair of side legs 32 and 33, one of which is supplied with a key-hole slot 34 receiving a headed pin 35 attached tothe casing 9 and the other of which is secured such as by a screw 36 to the casing.

From this latter arrangement itwill be @obvious that the ring can be lremoved and disinfected from time to tjmeby simply undoing the screw 36 and then sliding the ring latterly to allow the head of the pin 35l to elscape from the large end of the key-hole s ot. c

Considering this appliance set up as shown and the valve 7 regulated as is customary to control the stream of water through the pipe 2 from the mains, the operation'is as follows Y When one wishes to drink, the knob 22 is pressed down lby the thumb andthe one drinking bendsdown so that his mouth is opposite the ring. The instant the thumb knob isvr -pressed down the valve isfu'nseated with the result .that water flows intothe stand `pipe inthe manner herein before disT closedl and discharges through the opening 28 from" theV nozzle 27 so that the one drinking can `drinkirom the running stream adjacent thefring'. i

According to this'arrangement itwillbe obvious that the stream Ythrough the nozzle Visqdischarged by the .force of gravity'. acting on the head of water in the stand pipe andV equal to theV height. of the lower edge of the slot 18. With suoli a setting the stream delivered from the nozzle will not vary the slightest either in the distance which it is thrown orv in-aniount as under this set condition the pressure acting is that due to the head of water in the stand pipe and is entirely independent of the fluctuation in pressure at the main.

Should the pressure in the main increase above normal the stream is not affected in any way as an increase in the pressure in the main will simply cause lthe water to overflow through the slot 18 in the stand pipe through the openings 10. c Y Obviously the instant themknob isY released the valve seats and closes off the supply. Then this occurs there will 'be water trapped in the stand pipe to the height of the nozzle, which water will prevent. accumulated dust, etc., from'entering the'stand pipe'by way of the nozzle. 1

A `feature which I lwish to pointV out is that owing to the fact that the nozzle is inclined there is no possibility of the water falling from the lips and mouth ofthe one drinking dropping'back onI tothe head as where it falls and escapes to fthe bowlv Voccurs inthe vertical discharging'nozzles even place his mouth" against the guard ring.

In Fig. 7 of the drawing I have shown i' the device in a modified form with the valve removed.V In this construction the admission tube, instead of being a valve stem', is a stationary member secured to thev lower 'end of the stand pipe.' Y

The duct 24 opens 'directly to the interior of the extension 13. Y vWith' this form of construction'` the stream thrown from the nozzle is directly vunder the control of thehead of Ywater in the stand pipe and is'a constant one as by omitting the valve there 'is a constant flow from the main.

What l claim as my invention is i i f 1. A drinking fountain head connected directly with a water supply pipe of variable pressure and constructed to discharge a stream of water expelled by the force of gravity.

'2. A drinking. fountain head connected with a water supply pipe of variable pressure and constructed to deliver a constantv stream of water expelled by the force of gravity acting upon a constant head of a head of water can be maintained withiny the chamber. j y
